You're right. It's a little late. Let's just not do it. 🙄
Edit: this "too little too late" attitude is short sighted and egocentric. Even if limiting rent increases does not have a direct effect on even a majority of individuals today, it will surely someday have an effect on somebody. If the last 8 years of political and legal turbulence has taught us anything, it's that we need to legally codify things that are "common sense". Not limiting rent increases now because it doesn't have an effect now ignores the entirety of future circumstance. We need to codify laws now that make the future better for our children, if not for us. Not doing so is short sighted and egocentric. We need to think futuristic and humanistic. We need to think objectively rather than relative to our current state.
Fed interest rates are almost the exact same 5%. Is that a problem? If so, then saving 5% is a solution. Is it the whole solution? No. But nothing ever is.
Would a 5% raise solve your financial problems? Probably not. So then, would you turn it down? Financial success is multi-faceted. No one solution will get you there. Take what you can and build up layer by layer.
